OEM China Pumice Polishing Powder - FCZ925 Per Alloyed Metal Powder Used For Granite Muti Cutting Blades – SinoDiam

FCZ925 Per Alloyed Metal Powder Used For Granite Muti Cutting Blades

1. What is Pre-alloyed Powder

Pre-alloyed powders are harder, less compressible and hence require higher pressing loads to produce high density compacts. However, they are capable of producing high strength sintered materials. Pre-alloying is also used when the production of a homogeneous material from elemental powders requires very high temperatures and long sintering times. The best examples are the stainless steels, whose chromium and nickel contents have to be pre-alloyed to allow economic production by powder metallurgy.
